WASHER FOR GARRlAGE-AXLES.

SPECIFICATION forming part; of Letters Patent: No. 249,151. dated November 8 1881.

To all whom it may concern.- Be it known that l, Humor-11 1 ALLEN, a citizen of the United States of America. residingatlloston,intitecountyot'SuttolkandState of Massachusetts, have invented certain .now

and useful linprm'einents in Washers for (farriage ztxles and I do hereby declare the t'ollowing to he a. full, clear, and exact description of the invention, such to skilled in thc art. toflwhioh it: appertaiusto inah e ,nutl'use the same ielm'etee being had to the accompanying draw ing ores ot'relereuee marked thereon, whieh form apart of this specification.

This iurenti the devices used for ninintz'iiuin lotion between the axle of hub of a wheel revolving being to so arrange the parts I hat the huh shall beheld tightly hetween the washers upon the axle, but at the saint: time sna lhare a slight longitudinal motionthereon in connection with washers, as they may he alternatelyoonr pressed;. and the invention eonsists in the combination, with the axle and aearriage. of washers(composed ot'a sot't-nictal ring which receives the wear and a corrugated steel ring hy whiohytl supplied.

in the drawings, hi; the axle with a longitudinal section ol'the axle hex, showing the relative positions ot' tho sew eral parts asarraneed tor use. Fig. LVis a perspective View oi the eorru 3 shows both the g a proper roa carriage and the thereon, the ohieet sot't-nletal and corrugated rings in position. lorinine' the elastic washer.

A represents the axle; ii, the axle-hon. and (J the out by whioh the hox is held upon the axle. As all these parts are of strnction, they need no ih-tailot l lxpericnoo has tuneit axlehox olsuuh lengthns to completely till the space between the nutund the shoulders upon theaxle, so that the axle-hex lintl huh can have no end-play, the result is a hard-running rehiele, as the wheel eannot adjust itselii to the lateral inequalities oi" the sin-taco over which it tra'i'els without :arrying the whole carriage with it, thus prodnein-g a strain which notonly increases the power req aired to propel the vehicle, but lets iu juriously upon the wheels by working the spokes loose and otherwise cnusing ageneral (1 In order to avoid these diftienlties it; is coinmen to tllltls't) the axle-ho): shorteuthan the as will enable others' s and to letters or [leg on relates to improvements in axle-hex of re needed elastioitv is gated ring; and Fig. v

In order to construct a metallic washer that: shall possess the Ineossary qualifications to uieetlthe reqt'iireinouts ol' the situation, i use a a corrugated steel annulus or ring, a, oonstwcted as shown in Fig. 2-that is. after the. annulus has been out fltllll :Vshoetot' metal it is erimped radially so as topresont a waved peripheral line, and then tempered. This gives it great elasticity, as it may. uudt-r sutlicient pressure, he eoinpletoh llattouett out, but; will atoueeresumoils normal shape wln-nthe pressure is removed. As thecoi the steel ring would not. he suituhle one to receive the friction oi illtt'lltiS oi the rotating 'axle-hox,l phnj-o injtween wearing'a'ing, /i.
